SPECIFICATION forming' part of Letters Patent No. 620,575, dated March 7, 1899.

Application iled November 10., 1897. Serial No. 658,091 (No model.)

To aZZ .whom it may concern:

zen of the United States, residing at Monmonth, in the county of Varren and State of Illinois, have invented certainnew and useful Improvements in lVheeled Plows,ot which the following is a specification.

My invention relates to certain improvements in wheeled plows; and it consists in the new parts and new correlations and combinations of parts, hereinafter specifically pointed out and explained, for the general object of providingainore simple, convenient, and useful wheeled plow than has heretofore been constructed.

Referring to the drawings accompanying and forminga part of this specification, Figure 1 is a plan view of my wheel-plow. Fig. 2 is a landfside elevation of the same with the plow lowered. Fig. 3 is a furrow-side elevation of the same with the plow raised for transport-ation. Fig. 4 is a detailed View of the foot-lever raising and locking device with the plow lowered seen from the land side. Fig. 5 is the same with the plow raised. Fig. 6 is a detail view of the foot-lever raising and locking device with the plow lowered, seen from the furrow side with the link-bar broken away. Fig. 7 is the same, showing the position of the parts with'the plow lowered. Figs.

8, 9, lO, and 1l are 'detailyiews of arm 58,

arm 55, and foot-lever 59, respectively, which several parts are hereinafter specifically referred to.

In the drawings, l represents the main frame, consisting of at'steel parallel bars, connected by thearched bracket 1 in front and 4sustaining between the two rear ends a caster-wheel bracket2, which holds the sleeve 8, in which is journaled the vertical portion of the bent axle 4 ofthe caster-wheel 6. On the fuvrow side the main frame is supported by 'the furrow-wheel 5, journaled on the axle 7, which is bent upward, extends vertically for a convenient distance, and is then bent inward, forming at S an attachment for the pole-bracket P.

The vertical portion of the., agile 7 is jour- I e bracket 9, rigidf attached to the frame. C, The furrowwheel is raised and lowered with reference to Be it known that I, GEORGE E. EVANS, a citithe frame by means of the lever 10, which at its forward end is linked by the bar 11 to the sleeve-bracket 9, while it bears at 12 upon the vertical bar 13, rigidly ixed to the vertical part of the axle by brackets 14, above and below the play of the sleeve. The lever 10 locks in place by the toothed segment 1G on thev bar 13 engaging a spring-dog operated by a thumb-latch on the lever in the usual manner.

On thegland side the frame is supported by the landiwheel 17, journaled on the axle 18. The rocking axle 16 extends transversely under the main frame, is journaled on hangers 2O beneath said frame, andv extends beyond the landward side of the frame for a convenient distance.

The axle 19 may be locked in place by the rod 49 and the arm 48, attached to the furrowward end of the axle, as hereinafter described.

T-he axle 18 bea-rs the web 2l, terminating in the sleeve 22, journaled upon the axle 19. Awasher 23 serves to keep the sleeve 22 in the proper position on the axle. The frame is raised and lowered with reference to the land-wheel by means of the lever 24, rigidly aixed to the sleeve 22, whereby the sleeve is rotated on the axle 19, bringing the axle 18 either over or under the axle 19 or to anyintermediate position.

The lever 24 is locked in place by means of the toothed segment 25, rigidly attached to-the axle 19, and the usual spring-dog and,

thumb-latch.

From the upper end of the caster-wheel axle 4 extends furrowward the slotted arm 26, connected by the rod 27 with the inner extremity of the furrow-wheel axle 7. By this means the caster-wheel is caused to take a* direction in turning the plow such as will bring the rear of the plow into the proper position in the smallest possible time and space.

S is a seat sustained by a curved spring standard s on the rear landward side of the frame. The plow proper consists of the share 28, moldboard 29, landside 30, and beam 31.

Draft-power is applied at the end of the beam ,which is provided with the usual clevisv,front part of the frame and its central portion p tending to equalize its weight. iis also linked by the hoisting-link 40 (see Fi gs.

bracket-32. The plow is suspended beneath the frame by means of two arched rock-shafts or hails 33 and 34. The weight of the plow is borne almost entirely by the Vrear bail of the axle-hangers at each end, and its beam-bracket 35 on the rear downward-curving portion of the beam 31. The front bail 3,4 is journaled in suitable brackets 36 on the is under the Vfront part of the beam, working in the slotted bracket 37 thereon. The rear bail extends rearward from its frame-journals, is nearly the shape of a letter U, and its rear portion is so journaled on the plow-beam as to allow no play. 1 The 'front bail, on the contrary, extends forwardd from its .frame-v4 journal and works in aslot, as stated, allo/wing play. This play is riendered necessary n'ot only from the unequal lengths and angles of inclination to the beam of the'two bail-s, but also from the fact that, as hereinaftendescribed, both in raising and lowering the plow 'the front bail operates to raise and lower the point before the rear bail comes into opera-- tion. The rear bail 33 bears on itsleg on the furrow side an arm 38, disposed at right angles to the leg, to which is'attached one end of the strong coil-spring 39, pulling from the front curve of the frame, operating powerfully to raise the plow from the ground and The rear bail 4.and 5) to' the lower member of the hoisting- 1ever`4l, which is fulcrumed at its central portion on the bracket 4la on thefurrow side of the frame and extends upward therefrom, having its upper member somewhat bent forward, as shown. The upper member is provided with a horizontal slot 42 midway its length' and a hole 43 at its upper end. lThe second leverl 44 is fulcrumedat the same point .and revolyes in a plane parallel to that of the hoisting-lever 41 and operates it by means of the pin 45, working inthe slot 42. On the inner side of the lever 44 is a connecting-rod 46, operating the front bail 34 by means of the arm 47 thereon near its furrow- The apparatus described forms an independent means of raisingand lowering the plow, but not of locking'it in either position.

ing the second lever 44 backward. That lever operates at once upon the front bail through the rod 46 and the arm 47, tipping the front of the bail, and thereby the point of the plow, upward; but it does not exert any lifting power on the'rear bail till the pin 45 travels' backward and through the length of the slot 42 and engages the hoisting-lever 412 The backward .motion being then continued, the whole plow is raised and thrown srs since the pin has `to travel again'the length 'of the slot 42 before engaging the Ylever 41. By this means in raising the plow the point is invariably first tipped upward, which in the point is so depressed as to cause it to run into the ground to the required v depth of itself, thus in vpractice utilizing the draft of the machine for both purposes. The furrowward end of the rocking axle 19 extends beyoud/the frambeand bears the upward-extending arm 48.?.The rod 49, whichis shown in the drawings as disposed along the side of the frame, may be raised and attached at' its rear extremity to the upper end of the hoistinglever 41 by inserting its inwardly-bent end into the hole 43.l In that position it forms a Ac onnecting,-,link between the lever 41 and the arm 48am-the rocking axle 19, whereby said axle may be rocked, 4and the segment 25 and lever 24, with its spring-dog, forming a rigid connection with the axle 1S, its web 21, and sleeve 22, such rocking of the axle 19 raises and lowers the vframe with reference to' the and lowering ofthe plow from the ground.-

bracket on the rear of the frame and also ing the frame and plow when the rod 49 isattached to the lever 41.' If it be not desired scribed, it may be disposed as shown, its inward-bent end engaging an ear of the bracket 50 and holding the axle 19 in a perfectly rigid position, when the frame vcan beraised and lowered with reference tothe land-wheel by means of the lever 24, as already described.

I will now describe my'foot-leverlocking,

The lower rear edge of the arm 55 is carried backward beyond its pivot connection with the link 57, forming the shoulder 72.

the curved arm 55 theretothat is to say, the rear end link 57, the front end of the arm 58, and the rear end of the link-bar 61 are strung x5 on the bolt 66 in the order named from left to right. The foot-lever 59 is' strung on the saine bolt vbetween the arm 58 and the linkbar G1. The foot-lever 59 bears the inwardextending foot-rest or pedal 73 and an outzo ward-extending lug (32. The lower edge of the lug 62 forms a face or shoulder 747 which corresponds in lateral position and is adapted to engage with a corresponding shoulder 75 on the forwai lower edge of the arm 58 when the foot-lever 59 is thrown forward.

The lip 63 corresponds in lateral position with the curved arm 55, which has the shoulder 72 projecting upward and in contact with the lip 63 when the plow is lowered and in 3o the position shown in Fig. 5 when the plow is raised. When the plow is lowered, it is looked into position by the foot-lever 51, raising the arm 55 into the position shown in Fig. 4,

whereby the fulcrum of the lever-51, the link connection at A67, and the bolt 66 are in the same straight line. The link 57 and the curved arm thus operate as a rigid bar to resist any forward pull of the link-bar 61, whereby the f rontbail 34 is locked in place, and thereby 4c through the rod 46, the levers 44 and 41, and

the rear 'bail 33 the plow is also locked into position. When the plow is to be raised, the foot-lever 59 is thrown forward, bringing its lip G3 down upon the shoulder 72 of the arm `.ing the point 67 down ont of line with vcolt 66 and fulcrum 54 and unlocking the plow, which can now be raised either by means of the lever 44, as already described, or by forcing forward the foot-lever 59 until So its shoulder 74 is brought into contact with the corresponding shoulder 7 5 on the arm 58. In that position the lever 59 is practically a continuation of the arm 58, and pressure rocks that arm forward until it is in a horizontal 55 position, as shown infFig. 5. 'The forward tically, a rigid bar, preventing any further.

It is.'- io connected by the link-bar 61 to the arm 58 at y the same point at which the link157 connects whereby the plow is locked in its raised posiL tion. It being desired tol lower the plow, the foot-lever 51 is thrust forward, raising the bolt- '66 from its center and allowingshe plow to be lowered either by continued pressure upon the foot-lever 51 or by means of the handle 44, as 'before explained., Thus the plowcan be raised and lowered by alternate pressure on the foot-levers, which are adapted to be operated by the left and right feet of the operator as he sits in the seat described and that independently of the lever 44.

In practice it will not be found necessary to make use of the hand-lever 44except in exceptional cases, since the draft of the plow and the pull of the spring 39'so assist the op- 1. In combination, the plow, the wheeled -erator that very slight Afoot-pressure suces.
